PURPOSE:To enhance sensitively of a photosensitive body and to lower residual potential by forming an electric charge generating layer on a photoconductive layer. CONSTITUTION:The photosensitive body is formed by successively laminating on a conductive substrate the photoconductive layer containing an organic pigment (a) for generating charge and an electron donative charge transfer material (b), and the charge generating layer containing an organic pigment (c) for generating charge. If is preferred to use one or more kinds of tau, tau', zetaand zeta-type metal-free phthalocyanines for the pigment (c), and said phthalocyanines can be used for the pigment (a), and the charge transfer material (b) high or low molecular weight can be used for the material (b). Each of these layers can be formed successively on the conductive substrate by using a desired binder and applying a coating process. |
